Cian Fahey closely studies quarterbacks for Pre Snap Reads and has dedicated a 187-page catalogue to the position heading into the 2017 season. In it, Fahey utilizes a stat called accuracy percentage that strips away external factors -- throwaways, spikes, batted balls, Hail Mary passes and miscommunications -- to get a true measure of a quarterback's precision. Goff's accuracy percentage last year was 65.24 percent, last among the 33 quarterbacks analyzed.

Fahey also broke down accuracy in six ranges, and Goff fell within the bottom three in five of them. In Goff, Fahey saw someone with a relatively weak arm, shaky mechanics and poor footwork. He saw someone who couldn't spot underneath defenders and couldn't take his eyes off his first read in a timely manner. Fahey wrote that Goff "showed nothing during his rookie season that suggests he can even be a competent NFL quarterback, let alone a low-end starter."
